Last Tuesday, in this space, I published a piece arguing that a tollbooth is the honest version of what advertisers actually face.

A tollbooth has one operator, one posted price, and a name on the side of the building. What sits between a brand and a publisher has none of those things. I put the number at roughly half the dollar gone before anything reaches a page, I sourced it, and I braced for the pushback.you

The pushback came. It just came from the wrong direction.

Nobody wrote in to say the number was too high. Not one seller. Not one platform. Not one comms person with a prepared statement about how their take rate reflects the value delivered across the ecosystem.

What I got instead were three people who have actually set these prices, telling me I had been generous.

That is the whole installment. It is a short one, and I want you to feel the specific weight of it, because an industry that lets a critic undercount it in public is telling you something about what it expects to survive.

A former senior executive at PubMatic, who will remain unnamed, told me the numbers I published were too low.

I want to be precise about why that matters. This is not a disgruntled buyer or an academic with a model.

This is someone whose job was to sit on the selling side of the table and explain the take rate to the person paying it. He read the Thursday companion piece, the one laying out the five numbers to demand from an agency, and he wrote back within the hour.

His position was that the figures I published were conservative. DSP and SSP fees, he said, can be almost double what I had down, which in his read makes the picture worse for the advertiser and the publisher at the same time.

I told him I had to run averages, because that is what you do when you are describing an entire market rather than a single deal. He accepted that, and then said the thing that has been sitting in my chest for four days.

Even the averages get you to 51 percent of working media.

Read that twice. Not the outliers. Not some worst-case managed-service arrangement with a shop nobody has heard of. The average, run generously, in the direction most favorable to the industry, and slightly more than half the dollar is doing work.

Then he went further, and this is where the mask comes off. He described managed-service companies that knowingly take thirty percent or more on the DSP side alone. Not thirty percent total. Thirty percent at one stop, before the SSP takes its cut, before the exchange fee, before the data fee, before the verification fee, before whatever the reseller charges for the privilege of having existed in the path.

I have spent twenty-five months documenting this. I have had sell-side executives explain to me with enormous patience why the fee is complicated. I have never once had one of them tell me my number was too low.

Barry Green has been on record with me for three rounds now, by name, with a note attached that I will not soon forget. He told me I could always name him because he is at the end of his career, at the end of his days on this planet, and nobody can hurt him.

That is the posture that gets you the real number. He put the middleman take at fifty percent, and it has held across every round I have put to him.

But the line everybody skipped is the one he added last, almost as an afterthought, when I confirmed the arithmetic before the tollbooth piece ran. He said the direct path is better for publishers if they can get approved.

Four words doing an enormous amount of work.

Because that is the actual architecture. The escape route exists. Every seller in this business will tell you, correctly, that a publisher who goes direct keeps dramatically more of the dollar. And then the same structure that charges the toll also operates the approval process for the road that avoids the toll.

I am not going to open that door all the way today. That is Wednesday's lane, and this column stays on money. But note where the door is. The fee you cannot audit and the access you cannot obtain are administered by the same people, and the second one is what makes the first one durable.

Within ninety minutes of the tollbooth piece landing, Tom Pachys, co-founder and CEO of EX.CO, replied with a sentence I have been carrying around ever since.

If I have a willing buyer, he said, he is happy to run the experiment.

So I put it back to him in writing that same afternoon. Find me the buyer. It does not have to be big. It does not have to be a household name. One campaign, one budget, every fee disclosed at every hop, published in full, with the arithmetic open.

That offer is still standing. It has been six days.

I want to be scrupulously fair here, because Pachys did not have to say anything at all, and most CEOs in his position said nothing. He volunteered.

He was the only person in the entire industry who responded to a piece about opaque fees by offering to make one campaign transparent.

But six days is six days, and the reason a fully-disclosed campaign is hard to produce is not that the technology is missing. The technology has never been the obstacle. Every hop in that chain knows its own number to four decimal places. It bills on it. What is missing is anybody's willingness to let those numbers sit next to each other on one page, because the fees are individually defensible and collectively indefensible.

Each toll is reasonable. The road is not.

Standing offer, open to anyone reading this: bring me a real campaign, any size, with every party agreeing to disclose their take, and I will publish the whole thing, with your name on it or without, your choice. I will publish it even if the answer makes me look wrong. Especially then.

How we reported this: this installment is built on direct email correspondence with four sources between August 14 and August 21, 2026, all of it in ADOTAT's possession, plus arithmetic published in the August 18 and August 20 issues. One source, a former senior executive at PubMatic, is described by role rather than name at ADOTAT's discretion; his correspondence is on file. Fee figures throughout are estimates and are labeled as such, and the composite stack is a range rather than a measurement, because no party in the chain publishes auditable take-rate data, which is the subject of the piece. ADOTAT has no financial relationship with any company named here, takes no paid placement in editorial, and is funded by subscriptions. The media audit consultancy quoted anonymously is one ADOTAT is separately reporting on, and its CEO had an interview scheduled with ADOTAT at the time of publication.
